*not applicable for freelancers

We’re looking for an AI Engineer to join our outsourcing team — not a pure ML researcher, but a pragmatic, data-driven backend engineer who knows how to put LLMs, vision APIs, and off-the-shelf models to work inside real products.

Most of our work isn’t training models from scratch — it’s understanding the business logic, collecting and cleaning data, wiring it into LLMs or services like AWS Textract, and shipping the result as a reliable API inside our existing platform.

If you’ve spent the last few years building APIs and integrations, you’re comfortable with data, and you’ve leaned hard into Cursor or Claude Code to deliver projects faster — this is for you.

What you’ll do

• Build and ship LLM-powered features: prompt design, data prep, passing context to the model, parsing and validating output, returning clean APIs.
• Design and implement integrations between our product and third-party AI services (OpenAI, Anthropic, Hugging Face models, AWS Textract, etc.).
• Take document-processing and computer-vision tasks end-to-end: ingest → Textract/vision API → post-process → structured output consumed by our backend.
• Write backend services and APIs in Node.js (our primary backend), dropping into Python when a task calls for it (model work, data scripts, fine-tuning).
• Fine-tune existing models and prompts — not from scratch, but iterating on what’s already in place to get better accuracy, cost, or latency.
• Do the unglamorous but critical work: data collection, cleaning, transformation, pattern-finding — often by letting an LLM do the heavy lifting on structured and unstructured input.
• Maintain and improve existing AI and automation workflows already running in production.
• Monitor cost and performance of model/API usage, propose optimizations, and forecast costs for new features.
• Prepare and present demos and solution overviews to U.S.-based clients.
• Document architecture, prompts, and pipelines in Confluence.

What we’re looking for

• 2+ years shipping production backend systems, with meaningful hands-on experience integrating LLMs or AI APIs into real products.
• Strong in Node.js with the flexibility to work in Python — or a Python engineer who’s comfortable committing Node.js code. We need someone fluent on both sides; pure-Python candidates won’t be a fit.
• Solid grasp of algorithms and data structures — enough to write custom logic when an LLM or library can’t cover the case.
• Real experience with LLM integrations: OpenAI, Anthropic, or similar. Prompt engineering, function/tool calling, structured output, retrieval, evaluation.
• Familiarity with the Hugging Face ecosystem — picking models, running inference, fine-tuning where it makes sense.
• API and integrations background: REST, auth, webhooks, rate limits, retries, idempotency — the stuff that makes integrations not break at 2 a.m.
• Comfortable with data work: collecting, cleaning, transforming, and analyzing data (SQL, pandas, or the Node equivalents).
• Working knowledge of AWS — especially Textract, Lambda, S3, and the services around document and data pipelines. Bonus for Athena, Glue, Kinesis, SageMaker.
• Exposure to NLP and Computer Vision concepts — enough to pick the right tool and evaluate results, not necessarily to train SOTA models.
• Familiarity with CI/CD and deploying AI-powered services to production.
• Experience building chatbot workflows — conversational flows, multi-turn logic, context management — is a plus, as this is among our planned projects.
• AI-native delivery workflow. You use Cursor or Claude Code daily and know how to ship a project with minimal hand-written code — scoping work for the agent, reviewing generated code critically, orchestrating multi-step tasks, and getting to shipped quality faster than a traditional workflow. If you can’t describe how you use these tools to deliver, this role isn’t the right fit.

Nice to have

• Experience fine-tuning open-source LLMs or vision models on domain-specific data.
• Background in fintech, healthcare, or construction domains.
• Experience with vector databases, RAG pipelines, or agentic workflows.

What we offer

• Competitive salary with regular reviews.
• Support for individual entrepreneurs with accounting assistance.
• Fully remote work.
• A clear path for professional development and growth.
• A friendly team environment and engaging team-building activities (online and offline).

Role Overview 

We are looking for a Senior / Lead Engineer with deep frontend and full-stack capabilities inside the Salesforce Commerce Cloud ecosystem. This is a senior IC role — not a manager, but a technical leader. You'll drive architecture and implementation decisions across client storefronts, own the frontend quality bar, and shape how our team builds within SFCC.

You'll work across SFCC's full surface area — PWA Kit, SCAPI, headless and hybrid architectures, and Business Manager — while bringing genuine frontend craft to every engagement. You won't be limited to SFRA cartridge work; the expectation is that you can reason across the stack and lead implementation from the presentation layer down through the platform APIs.

This role is right for someone who has grown past executing tasks and is ready to own outcomes — technically, communicatively, and on behalf of clients who depend on us.

Essential Functions

• Help to drive a frontend and full-stack development across active SFCC client engagements — including PWA Kit (React/Next.js), headless storefronts, hybrid implementations, and SFRA-based projects where required
• Own frontend architecture decisions: component structure, state management, performance, accessibility, and rendering strategy within the SFCC ecosystem
• Drive SCAPI and OCAPI integration design — payment providers, loyalty, marketing automation, OMS, and other third-party systems
• Serve as the senior technical voice in client-facing conversations — able to present architecture tradeoffs, set expectations, and instill confidence with technical and non-technical stakeholders alike
• Lead code reviews and define implementation standards; elevate the quality of work across the engineering team
• Mentor mid-level and junior engineers through pairing, review, and direct coaching
• Collaborate with delivery leads on scoping, sequencing, and risk identification — contributing to technical estimates and SOWs when needed
• Evaluate and adopt emerging SFCC capabilities (Composable Storefront, SCAPI extensions, Einstein) and help the team stay current

Qualifications

• 6+ years of professional software engineering experience, with meaningful tenure on SFCC platform projects
• Strong frontend engineering fundamentals — React (required), component architecture, CSS, performance optimization, and accessibility
• Hands-on experience with PWA Kit / Composable Storefront architecture; comfortable working in a headless or hybrid SFCC context
• Solid working knowledge of SFRA for maintenance, migration, and hybrid integrations — not the primary lens, but not foreign either
• Proven experience designing and implementing integrations via SCAPI and OCAPI
• Strong understanding of ecommerce fundamentals — catalog, promotions, checkout, OMS, and order lifecycle
• Clear, confident written and verbal communication; comfortable owning the technical narrative with clients
• Prior experience in an agency, consultancy, or multi-client delivery environment strongly preferred
• Demonstrated ability to lead — through influence, code quality, and example — without relying on a management title

Tools

Platform & Development: Salesforce Commerce Cloud, PWA Kit / Composable Storefront, SCAPI / OCAPI, SFRA, Salesforce Business Manager 

Frontend: React, Next.js, TypeScript, CSS/SCSS 

Version Control & Collaboration: Git/GitHub or GitLab, JIRA, Confluence 

Client Communication: Slack, Zoom 

Analytics & Monitoring: Google Analytics, Salesforce Einstein Analytics, or equivalent ecommerce analytics platforms 

Documentation: Google Workspace (Docs, Sheets, Slides) for specs, handoffs, and client-facing materials

You'll collaborate closely with platform engineers and business teams, occasionally joining business discussions to clarify technical requirements or explain implementation details.
 

What you'll work on

• Implementing and configuring platform deployments for enterprise customers
• Building integrations between the platform and client systems
• Working with internal teams to understand client requirements and translate them into technical solutions
• Contributing to implementation tooling, documentation, and repeatable deployment processes
• Troubleshooting and resolving issues during and after deployment
• Occasionally participating in client calls to gather requirements or provide technical guidance
   

What we're looking for

• Strong proficiency in Vue.js, Node.js, and TypeScript
• PostgreSQL/similar RDBMS and general data modeling knowledge
• Familiarity with cloud platforms (AWS, Azure, or GCP), multi-cloud exposure is valuable
• Clear communication skills - comfortable explaining technical concepts to non-technical stakeholders
• Ability to work independently and manage multiple implementation workstreams
• 5+ years of software engineering experience
   

Useful additions / nice to haves

• Experience with AI platforms or AI/LLM integration
• Familiarity with CI/CD pipelines and infrastructure-as-code
• React experience
• Background in enterprise software implementation or professional services
• Previous work in similar roles

Extra Nice to haves

• Prize-winning places at programming olympiads (IOI, ICPC, Google Code Jam, Facebook Hacker Cup) or regional competitions.
• High rating on coding platforms: LeetCode (Knight+ or 2000+ rating), HackerRank (Gold+), Codeforces (Expert+ or 1900+ rating).
• Participation in hackathons with a focus on algorithmic problems (for example, victories at HackMIT, AngelHack).

Про компанію

SaaS AI-платформа, яка дозволяє підприємствам налаштовувати та впроваджувати AI-рішення відповідно до своїх конкретних потреб. Платформна команда є ключовою для цього процесу — вона відповідає за інфраструктуру, спільні компоненти та внутрішні інструменти, від яких залежить вся інженерна команда.

Роль

Це інженерна позиція з впровадження з акцентом на практичну реалізацію. Ви будете займатися розгортанням, налаштуванням та інтеграцією платформи для корпоративних клієнтів, трансформуючи їхні вимоги у робочі рішення, які розгортаються в інфраструктурі клієнта.

Роль знаходиться на перетині продуктової розробки та customer success: технічно глибока, але з розумінням реальних потреб клієнтів.

Ви тісно співпрацюватимете з платформними інженерами та бізнес-командами, інколи беручи участь у бізнес-обговореннях для уточнення технічних вимог або пояснення деталей реалізації.

Чим ви будете займатися

• Впровадження та конфігурація платформи для корпоративних клієнтів
• Побудова інтеграцій між платформою та системами клієнта
• Співпраця з внутрішніми командами для розуміння вимог клієнтів і трансформації їх у технічні рішення
• Розвиток інструментів для впровадження, документації та повторюваних процесів розгортання
• Виявлення та усунення проблем під час і після розгортання

• Періодична участь у дзвінках із клієнтами для збору вимог або надання технічних консультацій

   

Наші очікування

• Впевнене володіння Vue.js, Node.js та TypeScript
• Досвід роботи з PostgreSQL або іншими реляційними СУБД, розуміння моделювання даних
• Знання хмарних платформ (AWS, Azure або GCP), досвід з multi-cloud буде плюсом
• Чіткі комунікаційні навички — здатність пояснювати технічні концепції нетехнічним стейкхолдерам
• Вміння працювати самостійно та керувати кількома потоками впровадження одночасно
• 5+ років досвіду в software engineering

Буде плюсом

• Досвід роботи з AI-платформами або інтеграціями AI/LLM
• Знання CI/CD процесів та infrastructure-as-code
• Досвід з React
• Досвід впровадження enterprise-рішень або роботи в professional services

• Попередній досвід у подібних ролях

   

Додаткові переваги

• Призові місця на олімпіадах з програмування (IOI, ICPC, Google Code Jam, Facebook Hacker Cup) або регіональних змаганнях
• Високий рейтинг на платформах: LeetCode (Knight+ або 2000+), HackerRank (Gold+), Codeforces (Expert+ або 1900+)
• Участь у хакатонах з фокусом на алгоритмічні задачі (наприклад, перемоги на HackMIT, AngelHack)
